COLLEGE STATION – The complicated life of Texas A&M sophomore quarterback Johnny Manziel, the 2012 Heisman Trophy winner, just got quite a bit more complex.

The NCAA is investigating Manziel on whether he was “paid for signing hundreds of autographs on photos and sports memorabilia in January,” ESPN’s Outside the Lines has reported.

According to an online ESPN.com story: “Two sources tell ‘Outside the Lines’ that the Texas A&M quarterback agreed to sign memorabilia in exchange for a five-figure flat fee during his trip to Miami for the BCS National Championship Game. Both sources said they witnessed the signing, though neither saw the actual exchange of money.”

An A&M official couldn’t be reached for comment this afternoon. The Aggies reported for camp today and are scheduled to hold a press conference – Manziel is supposed to participate – starting 11:30 a.m. Monday. They take the field for the first time under second-year coach Kevin Sumlin on Monday evening.
